Kajima’s BIM Theory & Methods

Abstract

KAJIMA [1] is one of the largest construction companies in Japan. We have been applying BIM to more than 350 projects in Japan for the last 4 years (740 projects worldwide). We believe that there is nothing comparable to this scale of BIM implementation in the world. What makes our BIM different from others is our collaborative approach both internally and externally. We plan when and how much BIM effort we assign to each project. In other words, we optimize our efforts to make our BIM efficient on each project, not only for ourselves, but for the industry as a whole. Flexibility is the essence of BIM collaboration. In general, it is said that front-loading is Key Success Factor (KSF) of BIM. However, we believe that the essence of KSF is to adopt BIM flexibly in each phase of each individual project.
